How does this formula work? We know there are (n)/2 even

**numbers**till n. For example there are two even**number**till 4 and there are three even**numbers**till 6. Sum of first k even**numbers**is k * (k + 1) Putting k = n/2, we get sum of first n/2 even**numbers****as**n/2 (n/2 + 1)**Average****of**first n/2 even**numbers**(or even**numbers**till n) = (n + 2)/2.
